+# Tkdr Library
+
+## Rust Tkdr Library for **applications**
+
+Part of the following developments:
+
+- [CloudMandala](https://rlung.librecloud.online/LibreCloud/CloudMandala#cloudmandala)
+- [Zteron](https://rlung.librecloud.online/LibreCloud/CloudMandala#cloudmandala)
+
+Includes applications definitions and functions for following areas:
+
+- Encrypt Data
+- Decrypt Data
+- Templating
+- UIDs
+- Randomkeys
+
+### Criteria
+
+In a basic application scenario this group or library collections are included together.
+
+Updating packages or dependencies shoud be keep in sync among <u>Cargo.toml</u> declarations.
+
+### How to use
+
+1 - Clone or download this lib in a path, better outside of target development
+
+2 - Get current version from <u>Cargo.toml</u>
+
+3 - <u>For each member of</u>  of **Macros Library** one line like the one below should be included in <u>target development Cargo.toml</u> (adjust version & path) and **use** whatever is need.
+
+```toml
+tkdr = { path = "../lib/tkdr" }
+```
+
